Description

TITRE : Conteneur de modules de batterie, et système de stockage de puissance électrique associé TITLE: Battery module container, and associated electrical power storage system
La présente invention concerne un conteneur de modules de batterie, comportant une structure de réception des modules de batterie, la structure comprenant un plancher, des parois périphériques s’étendant verticalement à la périphérie du plancher et définissant des coins supérieurs, des pièces de coin supérieures montées sur les coins supérieurs et faisant saillie au-dessus des bords supérieurs des parois périphériques, les pièces de coin supérieures présentant chacune une surface supérieure, la structure comportant en outre un toit s’étendant entre les coins supérieurs, le toit, les parois périphériques, et le plancher délimitant un volume intérieur de stockage de modules de batterie. The present invention relates to a battery module container, comprising a structure for receiving the battery modules, the structure comprising a floor, peripheral walls extending vertically at the periphery of the floor and defining upper corners, upper corner pieces mounted on the upper corners and projecting above the upper edges of the peripheral walls, the upper corner pieces each having an upper surface, the structure further comprising a roof extending between the upper corners, the roof, the peripheral walls , and the floor delimiting an interior volume for storing battery modules.
Un tel conteneur est destiné à contenir des modules de batterie pour offrir une source de puissance électrique déplaçable, propre à être installée temporairement ou en permanence sur un site requérant de la puissance électrique. Such a container is intended to contain battery modules to provide a movable source of electrical power, suitable for being installed temporarily or permanently on a site requiring electrical power.
De manière classique, il est connu de construire un système de stockage de puissance électrique en disposant, dans un conteneur parallélépipédique standard, des modules de batterie et une unité de gestion électrique et thermique des modules. Ce système de stockage est facilement déplaçable, notamment par transport routier, ferroviaire, maritime ou aérien. Conventionally, it is known to construct an electrical power storage system by arranging, in a standard parallelepiped container, battery modules and an electrical and thermal management unit for the modules. This storage system is easily movable, notably by road, rail, sea or air transport.
La structure du conteneur recevant les modules de batterie comporte généralement un plancher, des parois périphériques faisant saillie par rapport au plancher, et un toit plat qui ferme le volume intérieur contenant les modules de batteries. The structure of the container receiving the battery modules generally comprises a floor, peripheral walls projecting relative to the floor, and a flat roof which closes the interior volume containing the battery modules.
De manière normalisée, le conteneur est équipé, à ses coins inférieurs et supérieurs, de pièces de coin. Les pièces de coin inférieures font saillie vers le bas par rapport au plancher et les pièces de coin supérieures font saillie par rapport au toit. Ainsi, le conteneur peut être disposé sous un autre conteneur, les pièces de coin inférieures de l’autre conteneur prenant appui sur les pièces de coin supérieur du conteneur. In a standardized manner, the container is equipped, at its lower and upper corners, with corner pieces. The lower corner pieces project downward from the floor and the upper corner pieces protrude from the roof. Thus, the container can be placed under another container, the lower corner pieces of the other container bearing on the upper corner pieces of the container.
Un tel conteneur ne donne pas entière satisfaction, lorsque celui-ci est disposé à l’extérieur. Le toit du conteneur étant plat, les eaux de pluie qui tombent sur le toit sont susceptibles de stagner au-dessus du conteneur. Cette stagnation se produit particulièrement au centre du conteneur, en particulier dans les zones les plus éloignées des bords latéraux du toit. Such a container does not give complete satisfaction when it is placed outside. Since the roof of the container is flat, rainwater falling on the roof is likely to stagnate above the container. This stagnation occurs particularly in the center of the container, especially in the areas furthest from the side edges of the roof.
La stagnation des eaux de pluie peut provoquer dans certains cas une usure prématurée du conteneur, notamment en favorisant l’oxydation, voire en créant des trous qui communiquent avec le volume intérieur contenant les modules de batteries. Ceci peut être nuisible au bon fonctionnement du conteneur, puisque les modules de batterie sont sensibles à l’eau. En outre, l’aspect esthétique du conteneur est dégradé. The stagnation of rainwater can in certain cases cause premature wear of the container, in particular by promoting oxidation, or even by creating holes which communicate with the interior volume containing the battery modules. This can be detrimental to the proper functioning of the container, since the battery modules are sensitive to water. In addition, the aesthetic appearance of the container is degraded.
Pour pallier ce problème, il est connu par exemple de CN212461856U de disposer, au-dessus du conteneur, un toit pentu qui évite la stagnation de l’eau de pluie lorsque celle- ci tombe sur le conteneur. To overcome this problem, it is known for example from CN212461856U to have, above the container, a sloping roof which prevents the stagnation of rainwater when it falls on the container.
Une telle solution protège efficacement le conteneur. Cependant, elle n’est pas satisfaisante, car le conteneur ne peut être transporté qu’au-dessus d’une pile de conteneurs, sans pouvoir recevoir au-dessus de lui des conteneurs supplémentaires. Le toit pentu augmente le coût du transport, et rend plus difficile la manutention du conteneur. Such a solution effectively protects the container. However, it is not satisfactory, because the container can only be transported on top of a stack of containers, without being able to accommodate additional containers above it. The sloping roof increases the cost of transport, and makes handling the container more difficult.
Pour éviter les problèmes pendant le transport, le toit pentu selon CN212461856U ne peut donc pas être installé lors de l’assemblage du système de stockage et doit être seulement installé une fois le conteneur sur site. To avoid problems during transport, the pitched roof according to CN212461856U cannot therefore be installed during the assembly of the storage system and must only be installed once the container is on site.
Un but de l’invention est donc d’obtenir un conteneur de modules de batterie, qui soit très résistant aux intempéries, tout en étant simple et peu coûteux à transporter. An aim of the invention is therefore to obtain a battery module container, which is very resistant to bad weather, while being simple and inexpensive to transport.

For this purpose, the subject of the invention is a container of the aforementioned type, characterized in that the roof comprises at least one water evacuation region, the water evacuation region comprising at least two inclined sides between a lower edge and at least one upper point common to the two inclined sides, to allow a flow of water received on each of the inclined sides towards their lower edge, the water evacuation region being located in or under a plane defined by the upper surfaces of the upper corner pieces.

Un premier système 10 de stockage d’énergie électrique selon l’invention est illustré par la figure 1. A first electrical energy storage system 10 according to the invention is illustrated in Figure 1.
Le système de stockage 10 est destiné à être déplacé jusqu’à un site d’utilisation, par exemple par un véhicule routier tel qu’un camion, par un véhicule ferroviaire, ou/et par un véhicule maritime tel qu’un navire de transport. Il est destiné à être raccordé électriquement à un réseau d’utilisation d’énergie électrique sur un site d’utilisation et en alternance à un réseau de fourniture d’énergie électrique pour son rechargement. The storage system 10 is intended to be moved to a site of use, for example by a road vehicle such as a truck, by a railway vehicle, and/or by a maritime vehicle such as a transport ship . It is intended to be electrically connected to an electrical energy use network on a site of use and alternately to an electrical energy supply network for its recharging.
Comme illustré par la figure 1 , le système de stockage 10 comporte un conteneur 12 de modules de batterie, délimitant un volume intérieur 14, et une pluralité de modules de batterie 16 reçus dans le volume intérieur 14. Le système de stockage 10 comporte avantageusement un système 18 de gestion électrique et thermique des modules de batterie 16 (« Battery Management Module » ou « BMM » en anglais) et un système de sécurité 20. Dans cet exemple, le conteneur 12 contient par exemple entre 10 et 150 modules de batterie 16. Les modules de batterie 16, sont arrangés sous forme de colonnes et de rangées. Ils sont montés en série et/ou en parallèle pour délivrer à au moins deux bornes électriques 22 présentes sur le conteneur 12, une puissance électrique pouvant atteindre jusqu’à 4MWh pour des tensions allant jusqu’à 1500V. As illustrated by Figure 1, the storage system 10 comprises a container 12 of battery modules, delimiting an interior volume 14, and a plurality of battery modules 16 received in the interior volume 14. The storage system 10 advantageously comprises a system 18 for electrical and thermal management of battery modules 16 (“Battery Management Module” or “BMM” in English) and a security system 20. In this example, the container 12 contains for example between 10 and 150 battery modules 16. The battery modules 16 are arranged in the form of columns and rows. They are connected in series and/or in parallel to deliver to at least two electrical terminals 22 present on the container 12, an electrical power which can reach up to 4MWh for voltages up to 1500V.

The management system 18 is capable of controlling the voltage and the intensity delivered by each battery module 16 when supplying electrical power, and the power and intensity of electrical current delivered to each battery module 16, during the recharging battery modules 16.
Les bornes électriques 22 sont destinées à se connecter au réseau utilisateur (non représenté) pour la fourniture d’énergie électrique stockée dans les modules de batterie 16, et en alternance, à un réseau de fourniture de puissance électrique, pour le rechargement des modules de batterie 16. The electrical terminals 22 are intended to connect to the user network (not shown) for the supply of electrical energy stored in the battery modules 16, and alternately, to an electrical power supply network, for recharging the battery modules. battery 16.
Le système de sécurité 20 comporte par exemple des capteurs (non représentés) de détection de température ou/et de pression dans le volume intérieur 14, une source de gaz inerte 24, et une unité de commande 25, propre à délivrer le gaz inerte dans le volume intérieur 14 à partir de la source de gaz inerte 24, sur détection d’une augmentation de température ou/et de pression supérieure à un seuil donné dans le volume intérieur 14. The safety system 20 comprises for example sensors (not shown) for detecting temperature and/or pressure in the interior volume 14, a source of inert gas 24, and a control unit 25, capable of delivering the inert gas into the interior volume 14 from the inert gas source 24, upon detection of an increase in temperature and/or pressure greater than a given threshold in the interior volume 14.
Dans l’exemple représenté sur la figure 1 , le conteneur 12 comprend une structure 30 autoportante, destinée à définir le volume intérieur 14, et à permettre le transport conjoint des modules de batterie 16, du système de gestion de modules 18, et du système de sécurité 20 jusqu’à un site d’utilisation. In the example shown in Figure 1, the container 12 comprises a self-supporting structure 30, intended to define the interior volume 14, and to allow the joint transport of the battery modules 16, of the module management system 18, and of the system security 20 to a site of use.
La structure 30 comporte un plancher 32 monté sur un support de plancher 34. Elle comporte des parois périphériques 36 faisant saillie à la périphérie du plancher 32, les parois périphériques 36 étant supportées par des piliers verticaux 38 au coin des parois 36. Elle comporte en outre un toit 40 porté par une charpente de support 42 visible notamment sur la figure 3. The structure 30 comprises a floor 32 mounted on a floor support 34. It comprises peripheral walls 36 projecting from the periphery of the floor 32, the peripheral walls 36 being supported by vertical pillars 38 at the corner of the walls 36. It comprises in in addition to a roof 40 carried by a support frame 42 visible in particular in Figure 3.
La structure 30 du conteneur 12 est ici de forme polyédrique. En particulier, la structure 30 présente la forme d’un parallélépipède rectangle, s’étendant longitudinalement le long d’un axe longitudinal A-A’ qui est horizontal lorsque le conteneur 12 est posé sur un support horizontal. Le conteneur 12 présente par exemple une longueur supérieure à 2 m, notamment comprise entre 2,5 m et 15 m, une largeur supérieure à 1 m, notamment comprise entre 2 m et 4 m et une hauteur supérieure à 1 m, notamment comprise entre 2 m et 4 m. The structure 30 of the container 12 is here of polyhedral shape. In particular, the structure 30 has the shape of a rectangular parallelepiped, extending longitudinally along a longitudinal axis A-A' which is horizontal when the container 12 is placed on a horizontal support. The container 12 has for example a length greater than 2 m, in particular between 2.5 m and 15 m, a width greater than 1 m, in particular between 2 m and 4 m and a height greater than 1 m, in particular between 2m and 4m.
Le conteneur 12 est notamment un conteneur pieds dit « High Cube » de 6,058 m de longueur, 2,438 m de largeur et 2,896 m de hauteur. Cependant la présente invention s’applique à tout type de conteneur ayant des coins ISO (exemple 40 pieds (12 m), 10 pieds (3 m), etc.). Container 12 is in particular a so-called “High Cube” foot container of 6.058 m in length, 2.438 m in width and 2.896 m in height. However, the present invention applies to any type of container having ISO corners (example 40 feet (12 m), 10 feet (3 m), etc.).
Le plancher 32 est ici plan. Il supporte les modules de batterie 16, le système de gestion 18 ainsi que le système de sécurité 20 lorsqu’il est présent. Le plancher 32 délimite vers le bas le volume intérieur 14. Floor 32 is flat here. It supports 16 battery modules, 18 management system as well as 20 security system when present. The floor 32 delimits the interior volume 14 downwards.
Le support de plancher 34 comporte par exemple des poutres, notamment de type IPN, s’étendant longitudinalement le long des bords de la structure 30, et aux extrémités longitudinales de la structure 30, des traverses transversales raccordant les poutres longitudinales. The floor support 34 comprises for example beams, in particular of the IPN type, extending longitudinally along the edges of the structure 30, and at the longitudinal ends of the structure 30, transverse crosspieces connecting the longitudinal beams.
Le plancher 32 est monté en appui sur le support de plancher 34. Le support de plancher 34 est par exemple propre à être saisi par des organes de saisie d’une grue, en vue de soulever le conteneur 12 et de le déplacer. The floor 32 is mounted to rest on the floor support 34. The floor support 34 is for example capable of being gripped by the gripping members of a crane, in order to lift the container 12 and move it.
Le support de plancher 34 est muni de pièces de coin inférieures 46 s’étendant à chaque coin défini entre deux parois périphériques 36 adjacentes. The floor support 34 is provided with lower corner pieces 46 extending at each corner defined between two adjacent peripheral walls 36.
Les pièces de coin inférieures 46 présentent une surface inférieure 48 destinée à reposer sur le sol ou sur un autre support, le plancher 32 étant alors situé au-dessus du sol ou du support. The lower corner pieces 46 have a lower surface 48 intended to rest on the ground or on another support, the floor 32 then being located above the ground or support.
Dans cet exemple, chaque pièce de coin inférieure 46 est située sous un pilier vertical 38. In this example, each lower corner piece 46 is located under a vertical pillar 38.
Les parois périphériques 36 comportent deux parois verticales longitudinales 50A, 50B (la paroi 50B a été enlevée de la figure 1 , mais est visible notamment sur la figure 3), les parois longitudinales 50A, 50B étant disposées verticalement, parallèlement à l’axe A- A’, de part et d’autre de l’axe A-A’. The peripheral walls 36 comprise two longitudinal vertical walls 50A, 50B (the wall 50B has been removed from Figure 1, but is visible in particular in Figure 3), the longitudinal walls 50A, 50B being arranged vertically, parallel to the axis A - A', on either side of the axis A-A'.
Les parois périphériques 36 comportent en outre deux parois verticales transversales 52C, 52D s’étendant perpendiculairement à l’axe A-A’ et raccordant les parois longitudinales 50A, 50B entre elles aux extrémités longitudinales de la structure 30. The peripheral walls 36 further comprise two transverse vertical walls 52C, 52D extending perpendicular to the axis A-A' and connecting the longitudinal walls 50A, 50B together at the longitudinal ends of the structure 30.
Les parois longitudinales 50A, 50B et les parois transversales 52C, 52D délimitent deux à deux des coins de la structure 30. Elles délimitent vers l’extérieur le volume intérieur 14. Les parois longitudinales 50A, 50B et éventuellement les parois transversales 52C, 52D sont munies de portes mobiles permettant par exemple d’offrir un passage d’accès au volume intérieur 14 depuis l’extérieur du conteneur 12. The longitudinal walls 50A, 50B and the transverse walls 52C, 52D delimit the corners of the structure 30 in pairs. They delimit the interior volume 14 towards the outside. The longitudinal walls 50A, 50B and possibly the transverse walls 52C, 52D are provided with movable doors making it possible, for example, to provide an access passage to the interior volume 14 from the outside of the container 12.
Avantageusement, la structure 30 comporte également une cloison interne 54 au volume intérieur 14, délimitant dans le volume intérieur 14 une salle 56 de stockage des modules de batterie 16, et séparément, une salle 58 de commande, recevant le système de gestion 18 et le système de sécurité 20. Advantageously, the structure 30 also includes an internal partition 54 to the interior volume 14, delimiting in the interior volume 14 a room 56 for storing the battery modules 16, and separately, a control room 58, receiving the management system 18 and the security system 20.
Avantageusement, au moins une porte ménagée dans une paroi périphérique 36 permet d’accéder à la salle de stockage 56, sans avoir à ouvrir la salle de commande 58, et au moins une autre porte permet d’accéder à la salle de commande 58, sans avoir à ouvrir la salle de stockage 56. Advantageously, at least one door provided in a peripheral wall 36 allows access to the storage room 56, without having to open the control room 58, and at least one other door allows access to the control room 58, without having to open storage room 56.
En référence à la figure 3, la charpente de support 42 comporte une pluralité de longerons 60, et avantageusement une pluralité de traverses 62 raccordant transversalement les longerons 60 entre eux. With reference to Figure 3, the support frame 42 comprises a plurality of beams 60, and advantageously a plurality of crosspieces 62 transversely connecting the beams 60 to each other.
Au moins deux longerons latéraux 60 raccordent les piliers 38 parallèlement à l’axe A-A’. Au moins deux traverses d’extrémité 62 raccordent les piliers 38 transversalement à l’axe A-A’. At least two side rails 60 connect the pillars 38 parallel to the axis A-A’. At least two end crosspieces 62 connect the pillars 38 transversely to the axis A-A’.

In this example, the support frame 42 further comprises at least one additional spar 60A disposed between the side spars 60, and several additional crosspieces 62B arranged between end crosspieces 62. The spars 60, 60A and the crosspieces 62, 62B define, under the roof 40, at least one support surface 64 supporting the roof 40.
Les longerons 60 et les traverses 62 sont dimensionnés pour permettre le support du toit 40 et d’au moins un être humain équipé marchant sur le toit, l’être humain équipé pesant par exemple 100 kg. The longitudinal members 60 and the crosspieces 62 are dimensioned to allow the support of the roof 40 and at least one equipped human being walking on the roof, the equipped human being weighing for example 100 kg.
La charpente de support 42 comporte en outre des pièces de coin supérieur 70 destinées à faire saillie au-dessus des piliers verticaux 38, au-dessus du toit 40. Les pièces de coin 70 définissent une surface supérieure 72 plane, et horizontale lorsque l’axe A-A’ est horizontal. The support frame 42 further comprises upper corner pieces 70 intended to project above the vertical pillars 38, above the roof 40. The corner pieces 70 define a flat upper surface 72, and horizontal when the axis A-A' is horizontal.
Comme visible sur les figures 1 et 3, les surfaces supérieures 72 des pièces de coin 70 définissent un plan supérieur P du conteneur 12, aucun élément du conteneur 12 ne dépassant au-delà du plan supérieur P. As visible in Figures 1 and 3, the upper surfaces 72 of the corner pieces 70 define an upper plane P of the container 12, no element of the container 12 protruding beyond the upper plane P.
Le toit 40 est réalisé de préférence en métal, notamment en acier, et est avantageusement couvert d’un revêtement de protection, notamment d’une peinture antirouille. Selon l’invention, dans l’exemple de la figure 2, le toit 40 de la structure 30 comporte une région centrale 80 d’évacuation d’eau, munie d’au moins deux pans inclinés 82A à 82D et avantageusement, deux régions non inclinées 84, situées longitudinalement de part et d’autre de la région centrale 80. The roof 40 is preferably made of metal, in particular steel, and is advantageously covered with a protective coating, in particular an anti-rust paint. According to the invention, in the example of Figure 2, the roof 40 of the structure 30 comprises a central water evacuation region 80, provided with at least two inclined sections 82A to 82D and advantageously, two regions not inclined 84, located longitudinally on either side of the central region 80.
La région centrale 80 s’étend sur une longueur d’au moins 10%, de préférence d’au moins 20%, de la longueur du toit 40, prise le long de l’axe A-A’. The central region 80 extends over a length of at least 10%, preferably at least 20%, of the length of the roof 40, taken along the axis A-A'.
Dans l’exemple représenté sur la figure 1 , la région centrale 80 comporte quatre pans inclinés 82A à 82D définissant une pyramide. In the example shown in Figure 1, the central region 80 comprises four inclined sections 82A to 82D defining a pyramid.
En référence à la figure 2, la région centrale 80 comprend ainsi deux pans inclinés longitudinaux 82A, 82B, d’inclinaisons dirigées latéralement, respectivement vers les parois longitudinales 50A, 50B, et deux pans inclinés transversaux 82C, 82D d’inclinaisons dirigées longitudinalement, respectivement vers les parois transversales 52C, 52D. With reference to Figure 2, the central region 80 thus comprises two longitudinal inclined sections 82A, 82B, with inclinations directed laterally, respectively towards the longitudinal walls 50A, 50B, and two transverse inclined sections 82C, 82D with inclinations directed longitudinally, respectively towards the transverse walls 52C, 52D.
Chaque pan incliné 82A à 82D présente ici une forme sensiblement triangulaire définissant un point supérieur commun 86 aux quatre pans inclinés 82A à 82D. Each inclined section 82A to 82D here has a substantially triangular shape defining a common upper point 86 to the four inclined sections 82A to 82D.
Chaque pan incliné 82A à 82D comporte un bord inférieur 88 et deux arêtes 90, 92 convergeant depuis les extrémités du bord inférieur 88 vers le point supérieur 86. Each inclined section 82A to 82D has a lower edge 88 and two edges 90, 92 converging from the ends of the lower edge 88 towards the upper point 86.
Les bords inférieurs 88 des pans inclinés longitudinaux 82A, 82B s’étendent le long des parois longitudinales respectives 50A, 50B, au-dessus de ces parois, notamment sur la surface supérieure définie par les longerons longitudinaux 60. The lower edges 88 of the longitudinal inclined sections 82A, 82B extend along the respective longitudinal walls 50A, 50B, above these walls, in particular on the upper surface defined by the longitudinal beams 60.
Les bords inférieurs 88 des pans inclinés transversaux 82C, 82D s’étendent parallèlement aux parois transversales 52C, 52D, de préférence en regard d’une traverse 62. Ils délimitent, vers le centre du toit 40, les régions non inclinées 84. The lower edges 88 of the transverse inclined sections 82C, 82D extend parallel to the transverse walls 52C, 52D, preferably facing a crosspiece 62. They delimit, towards the center of the roof 40, the non-inclined regions 84.
La région centrale d’évacuation d’eau 80 est située totalement dans et sous le plan supérieur P défini par les surfaces supérieures 72 des pièces de coin supérieur 70 ou totalement sous le plan supérieur P. Elle ne dépasse pas au-dessus du plan supérieur P. The central water evacuation region 80 is located totally in and under the upper plane P defined by the upper surfaces 72 of the upper corner pieces 70 or totally under the upper plane P. It does not protrude above the upper plane P.
Ainsi, le point supérieur 86 est situé dans le plan P, ou en dessous du plan P lorsque le conteneur 12 repose horizontalement sur un support horizontal. Thus, the upper point 86 is located in the plane P, or below the plane P when the container 12 rests horizontally on a horizontal support.
En référence à la figure 4, la hauteur H1 du point supérieur 86, prise verticalement depuis la surface d’appui 64 définie sur les longerons 60, est inférieure ou égale à la hauteur H2 des surfaces supérieures 72 des pièces de coin supérieur 70, prise verticalement depuis la surface d’appui 64. With reference to Figure 4, the height H1 of the upper point 86, taken vertically from the support surface 64 defined on the longitudinal members 60, is less than or equal to the height H2 of the upper surfaces 72 of the upper corner pieces 70, taken vertically from the support surface 64.
La hauteur H2 est comprise entre 20 mm et 30 mm. La hauteur H1 garantit de garder une distance d’au moins 5 mm sous le plan P. Ainsi, la région centrale d’évacuation d’eau 80 n’interfère pas avec un conteneur additionnel qui serait posé par ses pièces de coin inférieures sur les pièces de coin supérieures 70 du conteneur 12. The height H2 is between 20 mm and 30 mm. The height H1 guarantees keeping a distance of at least 5 mm under the plane P. Thus, the central water evacuation region 80 does not interfere with an additional container which would be placed by its lower corner pieces on the upper corner pieces 70 of the container 12.
L’angle d’inclinaison de chaque pan incliné 82A à 82D par rapport à un plan horizontal est par exemple inférieur à 10°, et notamment compris entre 1 ° et 5° pour les dimensions usuelles d’un conteneur 12. The angle of inclination of each inclined section 82A to 82D relative to a horizontal plane is for example less than 10°, and in particular between 1° and 5° for the usual dimensions of a container 12.
L’aire occupée par les pans inclinés 82A à 82D de la région centrale d’évacuation d’eau 80 est ainsi avantageusement supérieure à au moins 3% de l’aire totale du toit 40, les aires étant prises en projection dans un plan horizontal. The area occupied by the inclined sections 82A to 82D of the central water evacuation region 80 is thus advantageously greater than at least 3% of the total area of the roof 40, the areas being taken in projection in a horizontal plane .
Avantageusement, pour renforcer la rigidité de la région centrale 80, et notamment la rigidité de chaque pan incliné 82A à 82D, le toit 40 comporte des entretoises de renfort 94, s’étendant entre la surface d’appui 64 et une surface inférieure du pan incliné 82A à 82D. Advantageously, to reinforce the rigidity of the central region 80, and in particular the rigidity of each inclined section 82A to 82D, the roof 40 comprises reinforcing spacers 94, extending between the support surface 64 and a lower surface of the panel. inclined 82A to 82D.
Dans l’exemple représenté sur la figure 2, le toit 40 comprend au moins une entretoise 94 située entre la surface d’appui 64 et chaque pan incliné 82A à 82D, de préférence au moins deux entretoises 94 espacées l’une de l’autre, interposées entre la surface d’appui 64 et chaque pan incliné 82A à 82D. In the example shown in Figure 2, the roof 40 comprises at least one spacer 94 located between the support surface 64 and each inclined section 82A to 82D, preferably at least two spacers 94 spaced from one another , interposed between the support surface 64 and each inclined section 82A to 82D.
Pour les pans inclinés longitudinaux 82A, 82B, les entretoises 94 sont disposées sur une surface d’appui 64 définie par une traverse 62. Pour les pans inclinés transversaux 82C, 82D, les entretoises 94 sont disposées sur la surface d’appui 64 définie par un longeron 60, en particulier par un longeron central parallèle à l’axe A-A’. For the longitudinal inclined sections 82A, 82B, the spacers 94 are arranged on a support surface 64 defined by a crosspiece 62. For the transverse inclined sections 82C, 82D, the spacers 94 are arranged on the support surface 64 defined by a spar 60, in particular by a central spar parallel to the axis A-A'.
Grâce à la présence d’entretoises 94 situées sous les pans inclinés 82A, 82B, la région centrale d’évacuation d’eau 80 est apte à porter un opérateur muni de son équipement (par exemple pesant 100 kg avec son équipement), sans déformation des pans inclinés 82A, 82B. De plus, la forme et l’inclinaison des pans inclinés transversaux 82C, 82D renforce la rigidité structurelle de la région d’évacuation d’eau 80, permettant à l’opérateur de marcher sur le toit 40, sans flambement des pans inclinés 82A à 82D. Thanks to the presence of spacers 94 located under the inclined sides 82A, 82B, the central water evacuation region 80 is able to carry an operator equipped with his equipment (for example weighing 100 kg with his equipment), without deformation inclined sections 82A, 82B. In addition, the shape and inclination of the transverse inclined sections 82C, 82D reinforce the structural rigidity of the water evacuation region 80, allowing the operator to walk on the roof 40, without buckling of the inclined sections 82A to 82D.
En référence notamment à la figure 1 , chaque région non inclinée 84 comporte au moins un panneau de toit horizontal 100 s’étendant longitudinalement entre le bord supérieur d’une paroi transversale 50C, 50D respective et la région centrale d’évacuation d’eau 80 et s’étendant transversalement entre les bords supérieurs des parois longitudinales 50A, 50B. With particular reference to Figure 1, each non-inclined region 84 comprises at least one horizontal roof panel 100 extending longitudinally between the upper edge of a respective transverse wall 50C, 50D and the central water evacuation region 80 and extending transversely between the upper edges of the longitudinal walls 50A, 50B.
Chaque région non inclinée 84 définit au moins une ouverture traversante 102 d’évacuation de surpression dans le volume intérieur 14, et pour chaque ouverture traversante 102, une plaque de déflagration 104 rapportée sur le panneau de toit 100 sur le pourtour de l’ouverture traversante 102, pour obturer de manière étanche l’ouverture traversante 102, en l’absence de surpression supérieure à un seuil calibré dans le volume intérieur 14. Each non-inclined region 84 defines at least one through opening 102 for overpressure evacuation in the interior volume 14, and for each through opening 102, a deflagration plate 104 attached to the roof panel 100 on the periphery of the through opening 102, to seal the through opening 102, in the absence of overpressure greater than a calibrated threshold in the interior volume 14.
Le panneau de toit 100 est supporté par les surfaces d’appui 64 définies sur les longerons 60 et les traverses 62. The roof panel 100 is supported by the bearing surfaces 64 defined on the longitudinal members 60 and the crosspieces 62.
Dans cet exemple, chaque ouverture traversante 102 traverse verticalement le panneau de toit 100. Le panneau de toit 100 comporte ici deux ouvertures traversantes 102 parallèles, situées de part et d’autre de l’axe A-A’, en projection dans un plan horizontal. In this example, each through opening 102 passes vertically through the roof panel 100. The roof panel 100 here comprises two parallel through openings 102, located on either side of the axis A-A', projected in a plane horizontal.
Chaque ouverture traversante 102 présente ici un contour par exemple polygonal, notamment rectangulaire. Each through opening 102 here has a contour, for example polygonal, in particular rectangular.
Les plaques de déflagration 104 sont rapportées à la périphérie des ouvertures traversantes 102. La fixation est configurée pour définir le seuil calibré de surpression au- delà duquel la plaque de déflagration 104 s’ouvre pour libérer partiellement l’ouverture traversante 102, et diminuer la pression à l’intérieur du volume intérieur 14. The deflagration plates 104 are attached to the periphery of the through openings 102. The fixing is configured to define the calibrated overpressure threshold beyond which the deflagration plate 104 opens to partially release the through opening 102, and reduce the pressure inside the interior volume 14.
Chaque panneau de toit 100, et chaque plaque de déflagration 104 rapportée sur le panneau de toit 100 est située sous le plan supérieur P défini par les surfaces supérieures 72 des pièces de coin supérieur 70. En outre, les plaques de déflagration 104 présentent une surface supérieure située verticalement sous le point supérieur 86 des pans inclinés 82A à 82D. Each roof panel 100, and each deflagration plate 104 attached to the roof panel 100 is located under the upper plane P defined by the upper surfaces 72 of the upper corner pieces 70. In addition, the deflagration plates 104 have a surface upper located vertically under the upper point 86 of the inclined sections 82A to 82D.
Grâce à la présence de la région centrale d’évacuation d’eau 80, l’eau de pluie qui tombe au niveau de la région centrale d’évacuation d’eau 80 est évacuée naturellement vers les bords latéraux du conteneur 12 grâce aux pans inclinés 82A, 82B, et à l’écart du centre du toit 40 par les pans inclinés 82C, 82D. Thanks to the presence of the central water evacuation region 80, the rainwater which falls at the central water evacuation region 80 is naturally evacuated towards the side edges of the container 12 thanks to the inclined sides 82A, 82B, and away from the center of the roof 40 by the inclined sides 82C, 82D.
Ainsi, l’accumulation d’eau au centre du toit 40 est supprimée, ou est au moins très significativement diminuée. Ceci limite les risques de stagnation d’eau, et donc de dégradation du toit 40 du conteneur 12 en son centre. La formation par corrosion de trous nuisant à l’étanchéité du conteneur 12 est donc évitée. Thus, the accumulation of water in the center of the roof 40 is eliminated, or is at least very significantly reduced. This limits the risks of water stagnation, and therefore damage to the roof 40 of the container 12 in its center. The formation by corrosion of holes harming the tightness of the container 12 is therefore avoided.
Le conteneur 12 présente donc une durée de vie plus importante, une fiabilité accrue des modules de batterie 16 qu’il contient, puisque ceux-ci ne sont pas exposés à l’humidité. En outre, il présente un aspect esthétique extérieur amélioré, même s’il est soumis à des intempéries. The container 12 therefore has a longer lifespan and increased reliability of the battery modules 16 it contains, since they are not exposed to humidity. In addition, it presents an improved exterior aesthetic appearance, even if subjected to bad weather.
La région centrale d’évacuation d’eau 80 étant située sous le plan P défini par les surfaces supérieures 72 des pièces de coin supérieur 70, elle n’interfère pas avec le transport normal du conteneur 12. En particulier, le conteneur 12 peut être transporté sous d’autres conteneurs d’une pile de conteneurs, en recevant, sur ses pièces de coin supérieur 70, des pièces de coin inférieur d’un autre conteneur. Ceci permet notamment son chargement sur des navires, réduisant ainsi les coûts de transport. The central water evacuation region 80 being located under the plane P defined by the upper surfaces 72 of the upper corner pieces 70, it does not interfere with the normal transport of the container 12. In particular, the container 12 can be transported under other containers of a stack of containers, receiving, on its upper corner pieces 70, lower corner pieces of another container. This allows it to be loaded onto ships, thus reducing transport costs.
Dans une variante, visible sur la figure 5, les pans inclinés longitudinaux 82A, 82B présentent, en projection dans un plan horizontal, une aire supérieure à celle des pans inclinés transversaux 82C, 82D. L’aire des pans inclinés longitudinaux 82A, 82B est notamment supérieure à plus de 200% de l’aire des pans inclinés transversaux 82C, 82D. In a variant, visible in Figure 5, the longitudinal inclined sections 82A, 82B have, in projection in a horizontal plane, an area greater than that of the transverse inclined sections 82C, 82D. The area of the longitudinal inclined sections 82A, 82B is notably greater than more than 200% of the area of the transverse inclined sections 82C, 82D.
Les pans longitudinaux 82A, 82B délimitent entre eux un bord supérieur 120 horizontal, s’étendant parallèlement à l’axe A-A’ et définissant une pluralité de points supérieurs 86 de la région centrale d’évacuation d’eau 80. Le bord supérieur 120 s’étend entre les arêtes 88, 90 de chaque pan 82A, 82B. The longitudinal sections 82A, 82B delimit between them a horizontal upper edge 120, extending parallel to the axis A-A' and defining a plurality of upper points 86 of the central water evacuation region 80. The upper edge 120 extends between the edges 88, 90 of each panel 82A, 82B.
Comme précédemment, le bord supérieur 120 ainsi défini est situé dans le plan P, ou sous le plan P défini par les surfaces supérieures 72 des pièces de coin supérieur 70. As previously, the upper edge 120 thus defined is located in the plane P, or under the plane P defined by the upper surfaces 72 of the upper corner pieces 70.
Les pans inclinés longitudinaux 82A, 82B présentent ainsi un contour en forme de trapèze, alors que les pans longitudinaux transversaux présentent un contour triangulaire. The longitudinal inclined sections 82A, 82B thus have a trapezoid-shaped contour, while the transverse longitudinal sections have a triangular contour.
Une telle disposition optimise l’écoulement vers les parois longitudinales 50A, 50B, et non vers les régions non inclinées 84. La stagnation d’eau est donc encore plus limitée. Such an arrangement optimizes the flow towards the longitudinal walls 50A, 50B, and not towards the non-inclined regions 84. Water stagnation is therefore even more limited.
Dans la variante illustrée sur la figure 6, le toit 40 est dépourvu de région non inclinée 84. In the variant illustrated in Figure 6, the roof 40 does not have a non-inclined region 84.
La région d’évacuation d’eau 80 s’étend sur toute la longueur et sur toute la largeur du toit 40. The water evacuation region 80 extends over the entire length and width of the roof 40.
Dans cet exemple, en projection dans un plan horizontal, l’aire occupée par les pans inclinés transversaux 82C, 82D est de préférence inférieure à 10% de l’aire occupée par les pans inclinés longitudinaux 82A, 82B. In this example, in projection in a horizontal plane, the area occupied by the transverse inclined sections 82C, 82D is preferably less than 10% of the area occupied by the longitudinal inclined sections 82A, 82B.
Comme précédemment, toute la région d’évacuation d’eau 80, incluant le bord supérieur 120 est située dans le plan P ou sous le plan P. As previously, the entire water evacuation region 80, including the upper edge 120, is located in the plane P or under the plane P.
Dans cette variante, les ouvertures traversantes 102 d’évacuation de surpression sont ménagées directement dans les pans inclinés 82A, 82B et les plaques de déflagration 104 sont rapportées sur les pans inclinés 82A, 82B sur le pourtour des ouvertures traversantes 102, comme décrit précédemment. In this variant, the through openings 102 for overpressure evacuation are provided directly in the inclined sections 82A, 82B and the deflagration plates 104 are attached to the inclined sections 82A, 82B on the periphery of the through openings 102, as described previously.
Dans une variante, une couche d’isolant thermique, par exemple une couche fibreuse réalisée en laine de roche est disposée sous le toit 40, notamment, dans le volume délimité entre la surface d’appui 64, et les pans inclinés 82A à 82D. Cette variante favorise l’isolation thermique des modules de batterie 16, notamment lorsque la température augmente à l’extérieur du système de stockage d’énergie 10. In a variant, a layer of thermal insulation, for example a fibrous layer made of rock wool, is placed under the roof 40, in particular, in the volume delimited between the support surface 64, and the inclined sections 82A to 82D. This variant promotes thermal insulation of the battery modules 16, particularly when the temperature increases outside the energy storage system 10.
